Low-frequency spectra and scattering of pulsars towards the Gum Nebula with the MWA
Ting Yu, Zhifu Gao, Zhongli Zhang +1
Context. The Gum Nebula is a nearby ionised complex with sight-line-dependent pulsar propagation. Aims. We test whether a smooth ionised structure can explain low-frequency spectra…
Does the radio-active phase of XTE~J1810197 recur following the same evolutionary pattern?
Zhipeng Huang, Zhen Yan, Zhiqiang Shen +12
Magnetars are the most strongly magnetized compact objects known in the Universe and are regarded as one of the primary engines powering a variety of enigmatic, high-energy transie…
A study of 80 known pulsars at 185 MHz using MWA incoherent drift-scan observations
Ting Yu, Hongyu Gong, Zhifu Gao +4
A systematic study of 80 known pulsars observed at 185 MHz has been conducted using archival incoherent-sum data from the Murchison Widefield Array (MWA). The dataset comprises 48…
Renormalizable Cosmology Based on Gauss-Bonnet Theory with Torsion
Zirui Hu, Zhifu Gao, Haoxuan Sun +2
This paper focuses on renormalizable cosmology based on the Gauss-Bonnet theory with torsion. Within the framework of renormalizable quantum field theory, we study the matter field…
